Tell me, are you familiar with the Lewisian concept of True Myth?
In fact, this is frequently what we see in OT prophecy, where a later event alludes back to earlier events, thus bringing parallels and meaning. Generally, think of the adage that history repeats itself, now what can we not glean from putting those repeats in juxtaposition?
As an example, look at the Stone of Scone upon which Scottish Kings were crowned. It was stolen by Edward I and placed under the English coronation throne, and a few hundred years later a Scot ascended the throne of England.
Or a more Biblically relevant one, did you know that the Babylonian destruction of the First Temple, and the Roman destruction of the Second Temple, occurred on the same day of the Jewish calender?
Now Jesus' accounts are not modern history, but Hellenistic histories. Today we feign an attempt at objectivity, while loading our accounts with modern biases and presuppostions - just look at all these BLM takes on history, where even Winston Churchill is to be taken down. Hellenistic histories were similar, in that they were about getting the point across about events, what they mean, what they can teach us. They are less fantastic than the Romances, and are the direct antecedents of our modern tradition of historiography, but a noted difference is that we today affect a naturalistic viewpoint when writing history. So when writing on events in which a miraculous event is central, modern histories try to excuse, or debunk, or ascribe it to naturalistic causes. Noted examples are the miraculous rain out of season in the Marcommanic Wars (that the ancients unequivocally thought divine intervention), or the vision of Constantine (nowadays treated as a solar Halo often), or the numerous visions in battle - at Antioch in the Crusades, Edgehill in the English Civil War, Blood River in 1836, Mons in WWI (where they are either ignored politely, or ascribed to battle stress or suggestion), etc. Our 'literal history' is nothing of the sort really, just a specific paradigm of talking about past events that we think is more plausible based on our modern axiomatic prejudices, but often just as at odds with the accounts. For instance, we are happy to follow Lucan's account of the battle of Pharsalus as 'authentic history', but just ignore his story about a witch raising the dead just prior to it.
So I hope you see where I am coming from here. Now the primary sources for Jesus are the Gospels, which are essentially pretty standard Hellenistic histories - especially Luke. Secular scholars place them about 70-110 AD, so well within the recent memory of Jesus, who was killed under Pontius Pilate (who governed Judaea from 26-36 AD). So this would be about if I wrote on the 70s or 80s say. We also have Roman writers like Tacitus, Pliny the Younger and Suetonius that wrote close to the time and confirm some details, and more dubious evidence like the Nazareth decree.
Now further, the late date of the Gospels is only on account of the prophecy that the Temple is to be destroyed, so by standard practice prophecy is impossible and thus they had to have been written after 70 AD, when they knew the Temple was destroyed. This is quite silly, as it could have been prophesied even on secular grounds, as Judaea was restless and the Romans destroyed cities before, like Corinth, Numantia or Carthage. If we allow for prophecy, even more so. This drops our dates to the 50s AD, very close to the actual events. This is markedly different from Judges or Arthur say, written centuries after the lives of the figures involved.
So looking at the Gospels, they are pretty standard texts of the time - except that their subject matter is itself an utterly miraculous event, that the writers are fully aware of is miraculous and fantastic. When historians using standard practice then try and piece together the 'history' from this, they would jettison much of that - but essentially that is the heart of the account. As Paul said, without the cross and the empty tomb, they are meaningless. We are left with the standard all historians agree is fact or 'literally true', that Jesus of Nazareth existed, was baptised, lead a messianic movement, was crucified by Pilate (barring fringe nutjobs). This misses the whole point though of the texts themselves, and the meaning it held in the 1st century world of Second Temple Judaism and Hellenistic Mystery Religions.
The Gospels are therefore trying to tell a miracle story, and I see no strong grounds for rejecting its fundamentally miraculous narrative without undercutting its purpose. As an analogy, if I read about near-death experiences or meditation, and immediately medicalise it into merely brain chemistry, I am not really perceiving what those people experienced, but creating my own narrative thereof - which is largely a debunking or excusing their perception.
As a Christian, I firmly believe Jesus of Nazareth was God Incarnate, who died and rose again. I see this in the Gospels, where I see all the parallels of mythology, all the scattered leaves of human spirituality and religion, condensed into a Historic series of Events. I see mythology acted out in History, and via that history I can better understand both mythology and other history. Frankly, I think most of those Gospel miracles are Real, but the nature of historiography does not allow us to fundamentally present them that way, without falling into Apologetics or Preaching. History is not sure, the past is swathed in a blanket of time: The fall of Nineveh was redated 4 times, events taken as historical and them dropped before being taken up again (like Troy or the Milesians), and even recent events have several different accounts or ways of understanding them. When something strange happens in the modern world, we jump on it in empirical dissection, leaving a corpse of axiomatic assumptions and relegate investigation of it to Conspiracy Theorists or low budget sensational TV documentaries. This is merely our prism of socio-cultural interpretation, and there is no strong grounds to prefer it to another way of looking at things. It is about where you place your axioms, what you take as Self-Evident.
I extend Actuality to much of the Gospels, as they are texts close to their events, and aware that their subject matter beggars belief - hence the Church's early stress on Faith. They are written by reasonable men, not imaginitive Romances. CS Lewis made the point that those that think the Gospels merely stories have probably not read many stories, as they don't bear that narrative structure that well (although they do have literary structure within them). I make this point on the grounds of style and context, and as a consequence, the deep and glaring Mythological patterning and allusions within them, is strong support in my mind that Jesus of Nazareth reflects the Divine that all these stories were groping for. True Myth, essentially.
Footnote:
The Bible is composed of many different genres of writing. We have poetry and songs like Psalms, histories like the Gospels or Kings, more legendary Romance like Judges, etc. I have no way of knowing what is absolutely fact and what literary, but you can have an inkling. I don't think its meaning lies in it being an actual account of real events, but a lot of it I would class as that - with varying levels of probability. At least in the manner it was understood by their participants, as our view of what is 'actual' actually means projecting our viewpoint of how the world works and imposing it onto the accounts and understandings of people who thought in completely different ways about things. I don't think rejecting miraculous events out of hand is justified, merely a species of Presentism, and modern historians are often mired in contradiction on account of this; or why there have always been miracles recorded, but today we only see them in obscure corners of the internet or in hushed tones, as Naturalism is set-up as some form of Idol, while its feet are decidedly moist clay at best.
